If a stimulus, several times greater than the threshold stimulus is provided to a muscle fibre, it will

Options

  1. Acontract with a larger force
  2. Bcontract with a smaller force
  3. Ccontract with the same force
  4. Dundergo tetany.

Correct answer

C. contract with the same force

Step-by-step solution

A muscle fibre would contract only when it receives stimulation of certain intensity called threshold stimulus. Response of a muscle fibre to a stimulus is not proportional to its intensity. It is absent when the intensity is subliminal. Muscle fibre contracts to the maximum whether the stimulus has threshold value or supraliminal value.
